PINKING-VIACHINB SPECIFICATION forming part of Letters Patent No. 288,847, dated November 5.0, 1 85 3.

Application filed May 21, 1883. (No model.)

T all whom/,it may concer/1,:

Beit known that we, DAVID W. ODIORNE, of Elizabeth, in the county of Union and State of NewJerscy, and.ER NsT BRosnMAivN, of the city, county, and State of New York, have invented a new and useful Improvement in Pinking-Machines; and the following is declared to be a description of the same.

The pinking or scalloping of the edges of ro fabrics is commonly done with a cutting-tool having an edge in outline the 'same as the scal- Vlop to be made, the cutting being' done on a block of 'hard wood. 4Pinking-machines have also been made wherein the cutting-edge of i 5 the tool is formed upon the edge of a'roller or disk, and the cutting ofthe fabric is done between this edge and the surface of a hard-metal roller, and these pinking-machines have been operated by hand or other power. y 2o 4 `Ourinvention relates, essentially, to aswingl in gA and adjustable table to be operated in con-V nection with a pinkinglinachine having a revolving die-cutter and` metal roller; and the object of our invention is to pink or scallop the edges of fabrics, especially for umbrellas and parasols, and to do the same in a curved linethatshall represent the arc of a circle of any desired radius. We employ a table, upon the surface of whichthereare hinged adjustto suit the different sections of fabric used in umbrellas or parasols having different num-j bers of ribs, and said gages are adjustable lengthwise of the table, to accommodate sec tions of fabric for umbrellas, parasols, Ste., of different lengths or sizes. The pivotal center of the table is adjustable by a hand-wheel and screw-rod, and we provide a nut upon the screw-rod and a companion block sliding upon a dovetailed way on the under side ofthe table. The screw-rod is supported by bearings formed in standards secured to a bed. The table rests upon curved ways supported by columns secured to the bed of the machine. The pinking-machine that we employ is made with a revolving disk-cutter operating against a hard steel roller, and these are revolved by toothed wheels and a pulleyand belt.

In the drawings,'Figure 1 is an elevation of 5o our improved table.l` Fig. 2 is a plan of the able gages, the angle of which can be changedv table and pinking-machine, and Fig. 3 is a cross-section at the line x x of Fig. 2. i

A is the adjustable table for holding the fabric to be pinked, and B is the pinking-machine. The V-shaped gages a a" are vhinged together at b, and provided with holding-bars c cf, and said bars are slotted lengthwise. The table A has slots l 2 8 formed init, which are parallel to .,its length. The stems of the setscrews cl d pass through the slots 1 2 in the 6o table A'and in theholdingbars lc c', andthe heads 4L 'bear against the under side of the table, and the set-screws clamp the parts to the table. The pin of the hinge-j oint b has ahead on its underside, bearing against the under side of the table-top, and said pin is in the slot 3. By loosening the setscrews d d the Vshaped arms can be widened or contracted, or adjusted upon the surface of the table. Ve prefer to place a gage upon the table to indicate the 7o length of the sections of fabric as cut by the machine.

The standards e c are secured to a suitable bed,and they support the screw-shaft f and hand-wheel g upon the saine.

The circular track It is supported upon standards 5 6 7 S, secured to the bed, and we provide metal blocks/i t', fastened to said track h, and surrounding the screw-shaft fr The supports for the bed are thus rigidly connect- 8o ed together.'

There is a nut, l', upon the screw f, and said nut can be moved forward and backward by revolving the screw. There is a hole in the upper surface of the nut for the reception of 8 5 the center-pin Z upon the companion block m, and the block m, in its uppersurface, has a dovetailed groove tting the dovetailedway o on the under side of the table A. The block m has a projection-arm, a, extendingl to the 9o edge of the table A, and a screw, p, passing through the same, for clamping said block m and the way o firmly together. The position of the-nut c and block m and center-pin Z upon the screw-shaft f determines position of the center-pinupon which the table A swings; consequently the arc of the circle upon which the edge ofthe fabric is scalloped or pinked.

To shift the position of this nut and block, we bring the table into the position shown in Fig. Ico

2, parallel to the screw-shaft f, and insert the pin r through the table A into a hole in the block i, securely holding the table in position. We then loosen the set-screw 19 and revolve the hand-wheel g and screw-shaft f, and move the nut 7c and block m and pivot of the table to the desired distance from the pinkingtools.

The pinking tool or cutter s is mounted upon a shaft, and its periphery runs in contact with that of the hard-metal roller t, and both tool and roller are operated -by toothed wheels upon their respective shafts gearing together and driven by suitable toothed wheels and pulleys. These parts, being of well-known construction, do not require further description. v

The pivot of the table is to be set as heretofore described to make the edge of the fabric on the required arc of a circle, and the gages c a are set and clamped at the required angle to each other, and we take a piece of card-board of the same angle as the'gages and a, the right-hand or curved end of of a length to almost reach the pinking-tool s, the edge of the card-board being an arc of a circle from the pivot of the table, and lay the same upon the table, between""the gages a the table being swung toward the operator. Sections Iof silk or other fabric of the proper size and similar angle and the desired number of thicknesses are laid on the card-board, and

v another piece of card-board corresponding to the bottom piece is laid on top. The operator, with his hands on the top cardboard to press the fabric against the table, moves said table and the fabric toward the pinking-tool s, the fabric passes through, and the edge is cut with the desired figure, the table turning upon the pivotl as the revolving pinking-cutter and roller draw the fabrics through between them.

plane passing through the axis of the pinking-tools and roller; otherwise the fabric will not-be flat or remain in itsjplace between the gags...
